UFC on FOX 2 took place at Chicago’s United Center. The night’s main card aired on FOX, and six of the evening’s seven preliminary bouts aired on FUEL TV.

Johnson earned his check for a first-round knockout of the always-durable Joey Beltran. The former Strikeforce heavyweight, making his UFC debut, used a stiff jab to open the fight and then unleashed a devastating barrage of right hands that left Beltran out on his feet and earned Johnson the “Knockout of the Night.”

Oliveira, fighting for the first time at 145 pounds nearly earned his first-round submission win over Eric Wisely with a quickly applied heel hook. However, Wisely pulled free from the hold temporarily, only to be caught again in a deftly maneuvered calf-crusher. Wisely shouted out in pain from the rarely-seen maneuver, which secured Oliveira the evening’s “Submission of the Night.”

Lightweights Dunham and Lentz engaged in a back-and-forth affair, with Lentz earning the best of the early work. However, Dunham settled in and starting landing pinpoint strikes in the second frame, opening up a nasty cut under Lentz’s eye and possibly fracturing his orbital bone. The nasty wound worsened before Lentz could answer the bell for the third frame, and doctor’s waved off the contest. Still, the 10 minutes of work was enough for the fighters to earn the evening’s “Fight of the Night.”

As the UFC 189 tour made its last stop in Dublin, featherweight champ Jose Aldo was met with a torrent of abuse from the Irish fans. It might have been unpleasant, but it might also have been just what he needed.
